Fan Modules Overview
All the switches except C9300LM-48T-4Y have three internal hot-swappable fans. A powered switch should
always have more than one operational fan. The switch can operate with two operational fans and one
nonfunctional fan, but the failed fan should be replaced as soon as possible to avoid a service interruption due
to a second fan fault. A switch with one or more fans failed or removed will operate with fans at a faster speed,
producing increased sound.
Sharp edges on the fan module can cause serious injury. Keep fingers clear.
